What is the main difference between the traditional second-generation + night vision device and the thermal imaging night vision device?
1. In total darkness, thermal imaging night vision devices have obvious advantages
Since the thermal imaging night vision device is not affected by light, the observation distance of the thermal imaging night vision device is exactly the same in total darkness and normal light. The second-generation and above night vision devices must use auxiliary infrared light sources in total darkness, and the distance of auxiliary infrared light sources is generally only up to 100 meters. Therefore, in a very dark environment, the observation distance of the thermal imaging night vision device is much farther than that of the traditional night vision device.
2. In harsh environments, thermal imaging night vision devices have obvious advantages
In harsh environments such as fog and rain, the observation distance of traditional night vision devices will be greatly reduced. But thermal imaging night vision devices will be less affected.
3. In an environment where the light intensity changes greatly, the thermal imaging night vision device has obvious advantages
We all know that traditional night vision devices are afraid of strong light, although many traditional night vision devices have strong light protection. However, if the ambient brightness changes greatly, it will have a great impact on the observation. But the thermal imaging night vision device will not be affected by light. It is for this reason that top-of-the-line car night vision devices, such as those on Mercedes-Benz and BMW, use thermal imagers.
4. In terms of target identification ability, traditional night vision devices have advantages over thermal imaging night vision devices.
The main purpose of the thermal imaging night vision device is to find the target and identify the target category, such as whether the target is a human or an animal. The traditional night vision device, if the clarity is enough, can identify who the target is, and can see the facial features of the person clearly.
